Shadow DOM: Bit more details

Shadow Root: It is top of the shadow tree. Shadow Host: The element to which the tree is attached to. ShadowRoot: The host has a property called shadowRoot that refers to shadow root. Host: The shadow root has a host property that identifies host element. The shadow tree is separate from the element's children.
